Well, yes it should, but it doesn't. My version of gcc has a fix to make
builtin_alloca work, but it adds an extra overhead on function returns.
RMS says it will be fixed properly in gcc version 2.

It could be. The optimisation can use a lot of memory (though I
wouldn't have expected gnulib2 to be a problem). Try compiling the
troublesome modules without -O.
